S300SA

Speakers Overview

The Intervox S300SA is a general-purpose square speaker designed for wide frequency range applications. It features an Alnico magnet and a paper cone, delivering a nominal power handling of 0.25W with a maximum input of 0.5W. The unit operates at an impedance of 8 Ohms (±15%) and provides a sensitivity of 90 dB (±3dBA). Its frequency response extends up to 5000 Hz. The component utilizes solder lug terminals for connection and supports flush mount installation.

Speakers Feature Summary

• Utilizes Alnico magnetic structure for audio output
• Features paper cone construction
• Designed for flush mount installation
• Equipped with solder lug terminals

Speakers Applications

• General purpose audio reproduction
• Replacement for vintage miniature speakers
• Flush mounted audio devices

Speakers Procurement Notes

Verify RoHS compliance status before procurement as sources indicate compliance. Confirm terminal type matches existing circuit board layout. Ensure mechanical dimensions align with the designated flush mount enclosure space. Validate that the 8-ohm impedance is compatible with the driving amplifier output stage to prevent mismatch issues.

Speakers Selection Notes

Select this component when a square form factor is required for specific enclosure constraints. The 8-ohm impedance suits standard low-power audio circuits. Consider the 0.25W power rating for low-volume applications. The Alnico magnet offers specific tonal characteristics compared to rare earth alternatives available in the same product family.

Speakers Part Context

This part belongs to the Intervox line of general-purpose speakers. The series includes variants with different shapes and magnet materials, such as rare earth options. The S300SA specifically denotes the square frame configuration with Alnico magnetization and paper cone assembly, distinguishing it from round or rectangular counterparts.

Speakers Replacement Considerations

Direct substitutes may include other square speakers with matching 8-ohm impedance and similar physical dimensions. Verify that replacement units support the same flush mount mounting style and utilize compatible solder lug connections for seamless integration into existing assemblies.
